Özet

In this research, the influence of cotton gin waste (CGW), a by-product of agricultural industry, on soil and plant nutrient content were investigated. Pot experiment was carried out in greenhouse conditions and cotton gin waste applied into a clay soil in the pots as a fresh material, (dry weight basis 1000, 2000 and 4000 kg da(-1)). The study was consisted of two stages; the first 6 and the second 8 months periods. End of the 12 month in the second stage, bean plants planted into the pots as an indicator crop, and after 8 weeks growing period they were harvested. Soil sampling was performed two times, end of the 6 and 14 months and total organic carbon content in the soils and in two different aggregate sizes (2.0-1.0 mm and 0.25-0.05 mm) were determined. Total organic carbon significantly increased in the both soil and for the both stages (p < 0.001). Furthermore, there was significant increase (p < 0.001) between stages for both soils. Amendment of CGW significantly increased (p < 0.001) organic carbon in macro-aggregates (2.0-1.0 mm) whereas organic carbon in micro-aggregates (0.25-0.05 mm) significantly decreased (p < 0.001) in both stages for both soils.
